Federer and Serena power into quarter-finals

​Roger Federer delivered another stinging lesson to the next generation of men's tennis at the Australian Open on Monday, mauling Canadian Milos Raonic in straight sets to extend his record to a 35th consecutive grand slam quarter-final.

Federer completed his 6-4 7-6 6-2 masterclass in less than two hours under the lights of Rod Laver Arena, where defending champion Novak Djokovic had toiled for five in a huge scare against another Swiss, Stanislas Wawrinka, the night before.

Federer's emphatic win followed Serena Williams's 6-2 6-0 demolition of Maria Kirilenko, which set up her own generational battle with teenager Sloane Stephens.
